Re: st: Binning question

That is true of any binning method. My prejudices aside, I don't think
what you are seeking is clearly specified in statistical terms.

Thanks Nick,
I have some 300 size values that need binning for each of my 96 smpls.

With so many categories - the equal-width bin method will end up
splitting
certain observations into separate bins (so for example; 39.27 might
end

up in one bin, while 39.38 might end up in the next bin) depending on
where the bin range ends.
I was hoping for some code that might recognize certain size values as
belonging to the same distribution and bin them as such.
Hopefully someone might suggest some code to help me bin this data.
Cheers,
Mike.
Much easier and clearer just to use equal-width bins.

Statalisters,
I’m collecting various size measurements from multiple samples…
Smpl Size
01 39.38
01 45.26
01 48.81
02 39.27
02 45.28
02 48.94

Size is normally distributed and the variance is small. I want to
bin my
sizes into categories (eg “39”, “45” and “49”), for
further analysis.
I’d like to define the range for each category by using the SD of ea
